CALIBRATION
Before attempting the calibration procedure, the batteries must be fully charged and battery terminals
clean and tight. Move machine to an area that is perfectly level as measured by a spirit level or other
leveling device. An Ezcal hand-held device (MEC part # 90888) is required to carry out all calibration
procedures on the
GP102
Load sense control module.
Tilt Sensor Calibration
The integral tilt sensor of the
GP102
control module must be leveled to compensate for variations due to
installation and vehicle construction. This procedure must be done if the lower control box is ever
removed or repositioned, or if the
GP102
module is ever repositioned or replaced.
a.] Drive machine to level ground.
b.] Plug
EZcal
into connector P1 on load sense control module.

EZcal
from the load sense module.
Platform Load Calibration
Platform load calibration must be done if there are ever any significant repairs to the scissor assembly or
if the lift cylinder is removed and serviced or replaced. Also, if any of the components of the Platform
Load Sense System are replaced, the system will need re-calibration. During the calibration procedure
the vehicle platform is fully raised and lowered three times:
1. “DYNAMIC” calibration – fully loaded platform raised & lowered in one continuous movement. DYNAMIC
measurements are taken.
2. “LOADED” calibration – fully loaded platform raised & lowered with stops to take measurements. STATIC
measurements are taken.
3. “EMPTY” calibration – unloaded platform raised & lowered with stops to take measurements. STATIC
measurements are taken.
The following procedure must be followed COMPLETELY to calibrate the
GP102
; throughout the
procedure various checks are made – if any problem is detected the procedure stops and displays a
FLASHING failure message. Explanations of each message and suggested corrections can be found in
the section of this manual following the calibration procedure.
